Terry Fox was only seventeen when he got a cancer（癌症）．He must have felt hopeless when the doctor said his right leg would have to be cut off 6 inches above the knee．

     But to everyone's surprise，Terry Fox made up his mind to become a long﹣distance runner and do something about the cancer．What a dream！

     Although it seemed impossible，Terry decided to run across the whole country．He hoped to raise one million dollars for cancer research．Few believed he would make it．Anyway，on April 12，1980，Terry Fox began his Marathon of Hope．For the first days of his marathon，Terry Fox was alone．He started running at 4：30 am．Day by day，people began to realize that something big was happening on the lonely road．As people saw Terry，they stopped and donated（捐赠）money for cancer research．

     However，his health took a rapid turn for the worse several months later．He had to give up his marathon on September 1，1980．Terry died three months later，at the age of 22．In his short life，he raised ﹩24 million for cancer research﹣one dollar for each person in his motherland．

     Since his death，the yearly Terry Fox Run，first held in 1981，has grown to be the world's largest one﹣day fundraiser（筹资活动）for cancer research．
